On January 1, 2017, Park Rapids Lumber Company issued $80 million in 20-year, 10% bonds payable.  Interest is payable semiannually on June 30th and December 31st.  Bond discounts and premiums are amortized straight-line at each interest payment date.

a. Record the journal entry when the bonds were issued on January 1, 2017, make the necessary the journal entry to record the payment of bond interest on June 30, 2017, under each of the following assumptions:

1. The bonds were issued at 98. Round your answers to the nearest dollar.

2. The bonds were issued at 101. Round your answers to the nearest dollar.

b. Compute the net bond liability at December 31, 2017, under assumptions 1 and 2 above.  Round to the nearest dollar.

c. Under which of the above assumptions, 1 or 2 would the investor’s effective rate of interest be higher? Explain.

You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 47.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 21.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. How fast (in miles per hour) was car A traveling just before the collision? (This problem uses English units because they would be used in a U.S. legal proceeding.)

A power shovel with a dipper of two cubic yard capacity has a standard operating cycle time of 80 seconds. The excavated material which has a swell factor of 05 will be disposed by a dump truck with an 8 cubic yard capacity at a dump site 6 miles away. The average speed of the dump truck is 30 mph and the dumping time is 40 seconds. Find the daily standard production rates of the power shovel and the dump truck if both are operated 8 hours per day. Determine also the number of trucks needed daily to dispose of the excavated material.

In an experiment to investigate the performance of four different brands of spark plugs intended for use on a 125-cc motorcycle, five plugs of each brand were tested, and the number of miles (at a constant speed) until failure was observed. A partially completed ANOVA table is given.

Fill in the missing entries, and test the relevant hypotheses using a .05 level of significance. (Give the answer to two decimal places.)

TRANSPORTATION ENGINEERING: A multilane highway has four lanes (2 in each direction) and a measured FFS of 55 mph. One upgrade is 5% and 0.62 miles long. Currently trucks are not permitted on the road, but there are 2% busses in the directional volume of 1900 vehicles (PHF is 0.80). Local authorities are considering allowing trucks into the traffic stream. If this is done, they estimate 150 trucks will use this highway during peak hour. Before trucks, the driver population factor is 1, and it goes to 0.97 after trucks. What will be the level of service before and after trucks are allowed on the road.

A gravitational energy storage system uses a railcar system with a train that has a mass of 200,000 kg. The railroad track is 5 miles long and on a 10% grade (10 ft. elevation gain for every 100 ft. horizontal distance)

a. The electric locomotive uses 1.84 GJ of energy to propel the train up the side of the mountain. What is the efficiency of the system as it is “charging”?

b. The electric locomotive produces 1.44 GJ of electrical energy as it is descending the mountain. What is the efficiency of the system as it is “discharging”?

c. What is the “round-trip efficiency” (including charging and discharging) of the railcar system?

Observing the solar system model of concentric circles with center being the sun. The Earth is 1 AU from the sun. 1 AU is equal to about 150 million kilometers (93 million miles). Using a scale factor of 10¹⁰​ meters per astronomical unit (AU); let say that the Earth is 15 meters away from the sun. And let say, Earth takes on an average 365 days to complete a full cycle around the sun.

How far Earth travels in its orbit in one day?   What would be its speed?

Suppose you manage a local grocery store, and you learn that a very popular national grocery chain is about to open a store just a few miles away. Use the model of monopolistic competition to analyze the impact of this new store on the quantity of output your store should produce (Q) and the price your store should charge (P). What will happen to your profits? Explain your reasoning in detail. How and why do profits change? What could you do to defend your market share against the new store?
